An arrangement for Alto Flute & Piano of When the Saints.

A true jazz standard, it has been recorded by a great many other jazz and pop artists.

It is nicknamed "The Monster" by some jazz musicians, as it seems to be the only tune some people know to request when seeing a Dixieland band, and some musicians dread being asked to play it several times a night. The musicians at Preservation Hall in New Orleans got so tired of playing it that the sign announcing the fee schedule ran $1 for standard requests, $2 for unusual requests, and $5 for "The Saints". (This was in early 1960s dollars. By 2004 the price had gone up to $10.)

This tune and often the words are often used as a popular theme or rallying song for a number of sports teams (see When The Saints Go Marching In in sport). Most notably it is the main anthem of Southampton F.C. as they were originally known as St Mary’s YMA.

The Rhodesian Light Infantry, also known as "The Saints", used it as their regimental march.

In the Southern gospel genre the song is often associated with Luther G. Presley who wrote the lyrics, and Virgil Oliver Stamps, who wrote the music, whose version copyrighted by the Stamps-Baxter Music Company popularized it as a gospel song. A similar version was copyrighted by R.E. Winsett.
